SUMMARY:Forty Years of Change in a Serpentine Grassland, a talk by Lauren Hallett
LOCATION: Zoom registration: www.cnps-scv.org/npls-20240208
DESCRIPTION:\nZoom registration: https://us02web.zoom.us/meeting/register/tZwuce2spz4qE
 tJfI-9iP1_BVneCmErf0Vdw\nSerpentine grasslands support a relatively high pr
 oportion of California’ endemic plant diversity, providing a colorful displ
 ay every spring. Which species – and which colors – we see every year are h
 ighly variable. Here Professor Hallett shares findings from 40+ years of an
 nually observing species composition in a serpentine grassland at Jasper Ri
 dge Biological Preserve ‘Ootchamin ‘Ooyakma. She describes how gopher distu
 rbance and climate variability generating a shifting mosaic of species abun
 dances over space and time. While serpentine grasslands have largely resist
 ed invasion by non-native grasses due to their harsh soil conditions, she o
 utlines how atmospheric nitrogen deposition, especially in conjunction with
  high rainfall years, can facilitate invasion into the system. She will clo
 se with a discussion of management options to maintain serpentine plant div
 ersity into the future.\nLauren Hallett is an associate professor in the Bi
 ology Department and Environmental Studies Program at the University of Ore
 gon. Her lab aims to produce “usable” science to improve ecosystems.\nThis 
 talk will be live streamed on YouTube (https://www.youtube.com/ (https://ww
 w.youtube.com/)@CNPSSantaClaraValley - registration NOT required) and Zoom
